To all whom t may concern:

Be it known that I, JOSEPH SYLVAN, a citizen of the United States, and a resident of Cicero, county of Cook, and State of Illinois, have invented certain new and useful Improvements inVentilators for Saw- 'Iooth Skylightsgfandldo hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specication.

This invention relates to improvementsin ventilators for saw tooth skylights and consists-of the matters hereinafter. described and more particularly pointed out in the appended claims. Y

One of the objects of the present invention is to provide an efiicient ventilator construction for saw .tooth skylight which may be readily built into newskylights or may be readilyy applied to such skylights as are now in use without the necessity of making material changes therein. y

A further object of the invention is to so construct the ventilator that it will in no manner interfere with the passage of light through the panels of the skylight.

Still another object of the invention is to so arrange the parts of the ventilator with reference to the, skylight, that either kan intake of outside air or an exhaust of inside air may be had kas desired.

These objects of appear as I proceed vwith my specification.

In-thedrawingszv y. -ligure 1 is a transverse verticalsection through-a saw tooth skylight to which my improvedl ventilator construction has been applied. l

Figure 2 is an .enlargedfview of the top end of Figure 1 with some of therparts I thereof in a changed position.

Referring now in detail to that embodiment of the invention illustrated in the accompanyingdrawings z-'indicates a building roof and 5a indicates asa whole, a saw tooth77 skylight thereon. Said skylight'includes a face or wall 6 usually arranged at an angle of 30 relative to the plane of the building roof 5a, and an angularly disposed roof portion 7 arranged at a right angle to the plane of the face or wall 6. Saidk skylight may be made ,of anysuitable material the invention, aswell as Y the. many advantages thereof will more fully and is illustrated herein as made of concrete. The face 6 has an opening 8 therein ywhich is ldivided off into suitable lengths or spaces by horizontally spacedvbars 9, said bars. also acting to vreinforce the saw toothskylight as a whole. 10 indicates the prepared roofing covering the building roof and the roof section 7 of the skylight. Ordinarily, transparent panels 11 are associated with said opening 8 for the purpose of admitting natural light into the space or room below the skylight and said panels are'usually hinged along their top edge to the head 6a of the face wall 6 kso that the bottom edge thereof may be swung outwardly. The construction above described sets forth in general, the well known saw tooth skylight construction. v

Such skylights are generally recognized as the most eiiicient means for the entrance of natural light into the work shop or room beneath the same, and this is the primary consideration in their use, the ventilation aiforded thereby being secondary in consid.- eration and being of al minimum inefficiency when compared with other means mounted on the roof for Ventilating purposes. n In .applying my improved ventilator to such skylights,after removing the lightadmitting panel 11, I secure to the outer sur face of the head avof the face wall 6, a Vplu,- rality of longitudinally spaced substantially rectangular open frames 12. Each` frame includes downwardly and outwardly-'infclined rafter, barsf13, 13, with one -rafter connected to ashort leg 14 which is secured to the head 6a, and with the other rafterconnected to a longer leg 15,'the said legs being connectedV togetherin the planeb-fthe top part of the opening 8.l V.The frame is braced in the verticalmedian plane ofthe rafters, by an uprightV post 16 .which is securedl atv its bottomend'to the leg15 and near jitstopf'to the peak of the rafters, the top end, 16a4 projecting ra suitable distance above said peak; i A l Y Secured to the longerleg, 15,:of all of said frames near their. connection withl the associatedrafteribars 13 is a'longitudinally extending apron or plate 17, the outer margin of which is formed-toprovide a flange 18 which projects beyond. the plane'of the associated rafters. The other 4margin of said apron' terminates' about kmidway between the .ends of the legs 15 and is there formed tom part of the openingrS- is acombination` channel and flashing strip 20, said strip overlapping the roofing materialy onI thebuildsing root1 to make a Water tight joint at the f junction of the buildin f roof? and.` face Wall;
